Aragon 8008x3 No power

I believe they're fuses located inside the amp. Be careful if you take the top off to check. The filter caps do hold quite a charge for a while unless they have been discharged.
Generally, if you blow the main fuse, a serious problem exists, usually in the power supply. The internal fuses are "Rail" fuses protecting the individual amp output sections.
